COMPOSITION FOR PRODUCING ARTIFICIAL RUST.

No Drawing.

To all whom it may concern:

Be it known that I, CHARLES M. BOWMAN, a citizen of the United States, residing at Lebanon, in the county of Lebanon and State of Pennsylvania, have invented certain newand useful Improvements in Compositions for Producing Artificial Rust; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled 1n the art to which it appertains to make production of artificial rust by combining anduse the same.

The invention relatesto improvements in compositions for the production of artificial rust, and has for its object to provide an artificial coating of rust for the protection of exposed metallic surfaces against the formation of natural, destructive rust, and for the joining together of abutting metallic surfaces in a manner to prevent their separation under ordinary strains or stresses to which they may be subjected, without d'estroying or otherwise injuring the further or ture use of the articles or surfaces to which the composition has been applied.

The invention resides particularly in the certain well known inexpensive ingredients into a. semi-liquid or pasty condition, and then applying the reaction products of said 7 ingredients to the same, In any desired manvaried to any desired de parts; admixed with ner, to the exposed or joined surfaces to be coated or firmly secured together. In the production of the composition, the

several ingredients of the same are, for all practical purposes, used in the following proportions, but which proportions may be parting from the spirit 0 the mvention: finely c'omminuted iron, or other similar metalllc substances, fifty parts; ammonium chlorid, four (4) parts; sulfur, two (2) proxlmately ten per cent. (10%) strength in sufiicient quantity to make a.

hick, semi-liquid, or pasty mass.

Specification of Letters Patent.

' oming other surfaces, of fin e, without dediluted acetic acid, ap-

relatively Patented Feb. 13, 1917.

Application filed September 17, 1915. Serial N 0. 51,263.

The composition is applied in a manner to cover or coat the surface or joint, to be treated, the. thickness of the application of the same depending upon the probable strain or stress, in the case of a joining to- .gether of abutting or other connected surfaces, to which the same is to be subjected, and will harden, for all practical purposes, within a period of twenty-four hours.

It is obvious that the uses to which the invention are applicable, are practically limitless, and is especially adapted for securing nuts firmly in position on bolts, or metallic surfaces having threaded surfaces, as the action of the acid, in the composition efi'ects an assimilation of the particles of the metallic substance, with the ammonium chlorid and sulfur, into a relatively hard and compact mass, and one which adheres firmly to the surfaces to which it is applied.

Having thus fully described the invention, what is claimed, is

composition for producing artificial rust as a binding agent between metallic surfaces, consisting of the, reaction products of iron, ammonium chlorid, sulfur and an acid, substantially in the proportions described. t

2. A composition for producing artificial rust as a binding agent between metallic surfaces, and as a preventive for the formation of destructive natural ruston said consisting ely comminuted iron, fifty (50) parts; ammonium chlorid, four (4) parts; sulfur, two (2) parts, andv a ten per cent. (10%) solutionof acetic acid in sufiicient quantity to make a semi-liquid or pasty mass.
